FIG. 5 is a bottom view thereof.

The rear view is the mirror image of FIG. 3, and the left side view is identical to FIG. 4. The small circles visible in the vertically extending column of the device are bubbles of gas rising in a liquid contained in the column. FIG. 5 shows a pump which introduces these bubbles into the lower portion of the column.
